Wasn't the full name of the place Cowboys and Cowgirls? Just down the block from Rounds? And there was another bar too, whose name I can't remember.
I seem to remember one of the "customers" of note was Vladmir Horowitz whose
Adagio et Cantible figured prominently ( and fittingly) on the Interview With A Vampire soundtrack.
Those jeans, though... Seventies sweetie, early seventies.
